Use division to express the fraction in the form quotient + remainder / divisor. y^2-y-11/y-3

use long division or synthetic division
I will use long

y-3 times y=y^3-3y
subtract that from y^2-y-11
we are left with
2y-11
multiply y-3 by 2 and  get 2y-6
subtract that from 2y-11
get 5 as a remainder

answer is y+2+5/(y-3)

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.

What the heck i didn’t know
